Did anyone ever verify when her shift began?
On another note, I have great hope for Isabel even in light of the presser. I still don't know exactly what to think about what happened, who did it, or why. Parents are hinky but I don't know why. I think it is certainly good to question their behavior. I also think a stranger or someone acquainted with the Celis' (or a relative) could have taken her and got lucky on not waking anyone. Per this second theory, maybe even the Celis' have some suspicions but we don't know about them. Maybe they are involved with others or are not involved at all. I don't know!
I really thought the 7 question questionnaire they will be using could turn up some answers.
We watch a lot of the real whodunit shows on tv - it seems often they are following more than one good suspect or follow a good one only to rule them out at some point then another lead comes in leading to the real perp. I don't think it is all that unusual that LE would have some really good ideas and maybe even evidence but are teetering about if it's enough to make an arrest.
